Please tell me... Why is there river sludge in the front cylinder?
The rear piston and cylinder look pretty good for not operating within a year or more.The cylinders and heads are free! Apparently using daily sprays of penetrating oil for a few weeks caused the piston and cylinder to release their unnatural hold on each other. It was a surprise, really. I wanted to lift the engine onto a work bench. Working on an engine setting on the ground is simply not very good on my knees. I am still taking ibuprofin for the pain caused by my afternoon of work a few weeks ago.
Anyway, I gripped the cylinders, thinking the whole engine would lift. I wish I had a camera on my face when the cylinders just slipped up and off the pistons!
Looks like I have my work cut out for me. Hopefully I will not need to split the engine case, but first things first. The pistons, heads and cylinders need to be completely disassembled and checked. Hopefully they can be restored but I have a bad feeling about that front cylinder and piston.
